SKU (Stock Keeping Unit)

A unique code assigned to each product variant for identification and tracking. Helps organize your catalog and is commonly used in barcodes and inventory management.

A SKU — stock keeping unit, usually pronounced "skew" — is a short, unique code you assign to each distinct product variant so you can identify and track it precisely. It is the difference between "the blue medium one" and a code that means exactly that and nothing else.

Good SKUs are human-readable and systematic: a pattern that encodes the product line, the attributes, and the variant lets you read a label and know what it is without a lookup. That structure pays off everywhere — barcodes, pick lists, marketplace listings, and reports all key off the SKU.

In Ardent Seller each variant can carry its own SKU, so a candle that comes in three scents and two sizes has six distinct SKUs, each with its own price and stock level. Designing a clean SKU scheme early saves a painful renaming exercise once the catalog grows.
